Abstract
Abstract This research presents a low material costs (polymer) and low process costs (duplicate) concept, "An Integrated and Microstructured Flexible Hydrogen Fuel Cell l", a novel design of PDMS-based bendable electrodes with microstructures is proposed for flexible proton membrane fuel cells (PEMFCs). The design of the bendable electrodes incorporates micro-structured PDMS film to increase the reaction area and fuel path-way as well as Au conducting layers by E-Beam evaporation with chemically sturdy conjugation to the PDMS micro structures for electron conduction and fabrication of highly flexible Au/PDMS composite film electrodes. When proton exchange membrane fuel cell tests, anode and cathode use Au/PDMS film as electrodes. The catalyst layer is Pt/C. After cold pressing, we measure the MEA’s effects and study the phenomenon. A best fuel cell performance using Au/PDMS film with Pt/C and Nafion 211, a peak power density of 141 mA/cm2 and current density of 296 mA/cm2 at 70℃ with H2 and pure O2. In order to achieve Au/PDMS film electrodes have the flexible feature, the soft patterns of this research to develop new flexible battery application means to PDMS as a soft device substrate and with different types of soft material to replace the existing each unit cell components, technologies and issues to explore flexible means of selection and integrated device package of flexible application.
